DISK WHEEL.

Application filed March 19, 1925. Serial No. 16,716.

A further object of the invention is to pro' vide a disk wheel having a sound-deadening means incorporated in the construction there'- of, which functions to absorb and eliminate objectional and disturbing noises generated in the wheel when traveling at relatively high speeds.

A further and more specific object of the invention is to provide a disk wheel having flexible sound-deadening members engaging opposite sides of the central portion of the wheel disk thereby to damp or absorb all v1- bration of the wheel and thus to render it quiet-running. A further object is to provide a disk wheel having the tire rim-supporting or felloe flange or member independently formed and secured to the wheel disk, and between which flange and disk a sound-deadening means is interposed for the'purpose of absorbing obv jectional noises'or sounds generated 1n the wheel. The particular object of the invent on therefore is to provide an improved disk wheel. Y

Other objects of the invention will appear from the following description and the accompanying drawings and will be pointed out in the annexed claims.

In the drawings there has been disclosed a structure designed to carry out the various objects'of the invention but it is to be understood that the invention is not confined to the exact features shown as various changes may be made within the scope of the claims which follow.

In the drawings: 7

Figure 1 isla sectional elevation of a portion of an automobile wheel showing the in- 6 vention applied thereto;'

Figure 2 is a sectional view on the line 22 of Figure 1, partially broken away to show the relative position of the parts; and

Figure 3 is a perspective view of one of the 65 flexible sound-deadening washers or members removed from the wheel.

, the provision of flexible washers The novel disk wheel featured in this invention. preferably comprises a circular metallic disk 4 having a peripheral flange 5 adaptedto provide a seat for the usual tire rim 6 mounted thereon. The marginal edge of the flange 5 is preferably bent outwardly to provide an abutment 7 for the rim 6 when mounted on the disk.

An important feature of this invention resides in the novel means provided for deadening or eliminating. by'absorption, objectionable and undesirable noises which may be generated in the metallic disk when the wheel is traveling at certain speeds.

As shown in Figure 1, the disk 4 is provided -with a flattened central portion 8 which is apertured to receive a central sound-deadening member or hub 9, preferably of wood having an outwardly projecting peripheral flange 10. preferably integrally formed thereon. The means provided for absorbing the vibrations of the metallic disk 4 resides in or disks 12, preferably of fabricated material, which are mounted on the auxiliary sound-deadening hub 9 and adapted to engage opposite sides of the central portion 8 of the disk 4. An an nular plate or clamping member 13 is also mounted on the hub 9 and this clamping mem her is apertured to receive a series of studs or bolts 14, preferably having integral flanges or heads 15 provided thereon adapted to engage the clamping plate 13, as shown in Figure 1. A spacing washer 11 is peripherally mounted on the flange 10 of the hub 9, and this washer is similarly apertured to receive the studs 14. When the disk 4 has been positioned upon the auxiliary hub 9 between the sound-deadening members 12, the studs 14 will be inserted through aligned apertures provided in the several parts, thence through the wall of the usual brake drum 16 and through the flange 17 usually provided on the main hub 18 mounted on the axle 19.

Threaded nuts '21 are mounted on the ends of the studs 14 adapted to securely clamp the various parts together for operation as a unit. As shown in Figure 1, the thickness of the spacing washer 11 is-subst-antially equal to the thickness of the peripheral flange 10 of the sound-deadening hub 9 so that when the nuts 21 are mounted on the studs 14,- the several parts may be securely clamped together. The annular shoulder 20 provided on the hub 9 by means of the flange 10 will engage the adjacent sound deademing washer 12 thereby retaining it in proper position upon the main hub 18'. 1 I

Each stud 14 is preferably provided'with an oppositely extending end portion 22 5 adapted to receive an apertured saucer-like edge-portion 24 bearing against the surface of theirregularly shaped disk 4. Threaded nuts 27 are preferably mounted on the end portions 22 for securing theplates 23 and 25 to the wheel. The gap between the bore of the saucer-like finishing plate 23'and the periphery of the main hub '18 is closed by means of the curved hub plate 25 which is provided with a central aperture to receive the end of the hub 18. The usual hub cap 26 is received in threaded engagement with the end of the hub 18 and is adapted to engage the outwardly projecting edge ofthe plate 25, thereby to present a neat appearance to the wheel when mounted on the hub 18.

When it is desired to demount or remove the wheel from the hub 18, the cap 26 will first be removed from the end of the hub, after which the latter may be removed from theaxle 19. The nuts 21 are then removed from, the inner ends of the studs 14 after which the sound-deadening hub 9 carrying the disk, sound-deadening washers 12, finishing plate 23 and hub plate 25 may be removed as a unit, from the main hub 18. The hub 9 is preferably provided with a tapered bore to adapt it to snugly fit the tapered periphery of the hub 18. By the use of the auxiliary sound-deadenin hub 9 this novel disk wheel may readily be fitted to front or rear wheels, of'standard construction, by sim ly boring which it is to be mounted. Also by its use in conjunction with the fabricated washers 12, the wheel will be rendered substantiall sound-proof. I The various parts, mounte on the hub- 9 are preferably snugly fitted thereto so that when the disk 4 is removed from the main hub 18, the sound-deadening hub 9 will be removed therewith as a unit,

If desired, however, means (not shown) may be provided for securing it thereto.

It is to be understood that the main hub 18, flange 17 and brake drum'16 are of 01- dinary construction, such as are commonly employed in the construction of automobilewheels. To replace the old orspoke type of wheel with a disk wheel, it is only necessary to remove the usual hub plate 25 and the spokes from the main hub 18, after which the auxiliary hub 9 of the disk'wheel may be fit ed to the hub, 18 in place thereof, thereby pt oviding a very substantial and neat-appearing disk wheel.

To further render the wheel noiseless and quiet-running, 'a secondary sound-deademng 05 means is preferably provided 111 the outer portion of the wheel adjacent the tire mm the hub to fit the particular size 0 hub upon abut the flange flange 5. As shown in Figure 1, such means pre erably consists in the provision of a sound-deadening ring or member 28 which is interposed between the outer marginal ed 'e- 7/ portion 29 of the disk 4 and the inwardly finishing plate 23 which has its outer curved" rojecting flange 30 of the tire rim-supporttened together for operation as a unitby means of the rivets '31.

The sound-deadening washers or plates 12 and the outer member 28 used in the construcany vibration which maybe generated in the,

steel disk 4 when the wheel is" traveling at relatively high speeds. It is also to be understood that the number, shape and size of the sound-deadening members used' in the construction of each wheel may be varied, as required, toaccomplish the desired results without departing from the invention.
